gain is set to 0, the overvoltage stall function is disabled. The overvoltage stall protective
voltage setting 100% corresponds to the base values in the following table:

When the output current exceeds the overcurrent stall protective current during
acceleration/deceleration of the AC drive, the AC drive stops acceleration/deceleration
and keeps the present running frequency. After the output current declines, the AC drive
continues to accelerate/decelerate.
P9-05 (Overcurrent stall gain) is used to adjust the overcurrent suppression capacity of
the AC drive. The larger the value is, the greater the overcurrent suppression capacity will
be. In the prerequisite of no overcurrent occurrence, set P9-05 to a small value.
For small-inertia load, the value should be small. Otherwise, the system dynamic
response will be slow. For large-inertia load, the value should be large. Otherwise, the
suppression result will be poor and overcurrent fault may occur.
If the overcurrent stall gain is set to 0, the overcurrent stall function is disabled.
